I came up on gsr block with a micro polished and knife edged crank, LS eagle rods and .10 over itr pistons. block is bored .10 over.


the head I will be ising is a b16 head, P&P, vlat faved valves, duel springs and retainers, stage 2 jun cams, blox intake mani, 70mm tb with rc550's and adjustable fpr.

using a t3 or t4 turbo would it be safe to turbo? what hp would I be able to achieve on these internals? i will tune with erick's racing and im on s300

 

Are you really asking, in 2010, if it's okay to turbo a B-Series?

Realistically, on those pistons, you probably shouldn't be doing anything over 350whp. If you're feeling froggy, you can push it to a hair over 400whp if you wish.

Honestly, given that you're on cast pistons, you won't need anything larger than a T3/T4 60-trim or one of the larger GT28's, though a GT3076R or 60-1 would work as well as any of the Precisions of similar sizing.

1. Leave the fuel pressure at the factory setting.
2. Get a Walboro 255lph fuel pump.
3. Get larger injectors - 750cc will be plenty unless you change out to forged pistons.
4. Get a 3 or 4 bar MAP sensor.

Also, what TB do you actually have? Get one that doesn't stick open or cause idling issues so that your tuner doesn't hate his life that day.

 

everything and its mom can be turbo'd. I want to know if its practical to be a dd.

the pistons are after market p73 pistons and im running 550's already. I wanna know what the internals can handle at the compression those pistons are gonna put me at.

I have a omni power tb and it works fine no sticking.
ill be on pump gas as im a cheap bastard

should I just go with lower comp pistons to be on the safe side?
